摘要:
The present invention provides methods for preventing, managing, treating and/or ameliorating a Respiratory Syncytial Virus (RSV) infection (e.g., acute RSV disease, or a RSV upper respiratory tract infection (URI) and/or lower respiratory tract infection (LRI)), otitis media (preferably, stemming from, caused by or associated with a RSV infection, such as a RSV URI and/or LRI), and/or a symptom or respiratory condition relating thereto (e.g., asthma, wheezing, and/or reactive airway disease (RAD)) in a subject, comprising administering to said human an effective amount of one or more antibodies that immunospecifically bind to one or more RSV antigens with a high affinity and/or high avidity. In some embodiments, one or more antibodies comprise a modified IgG constant domain, or FcRn-binding fragment thereof resulting in longer in vivo serum half-life. In particular embodiments the methods of the invention comprising administering to subject an effective amount of one or more modified antibodies that immunospecifically bind to one or more RSV antigens with an association rate (kon) of at least 2×105 M−1 s−1 and a dissociation rate (koff) of less than 5×10−4 s−1.
摘要:
The present invention encompasses novel antibodies and fragments thereof which immunospecifically bind to one or more RSV antigens and compositions comprising said antibodies and antibody fragments. The present invention encompasses methods preventing respiratory syncytial virus (RSV) infection in a human, comprising administering to said human a prophylactically effective amount of one or more antibodies or fragments thereof that immunospecifically bind to one or more RSV antigens, wherein a certain serum titer of said antibodies or antibody fragments is achieved in said human subject. The present invention also encompasses methods for treating or ameliorating symptoms associated with a RSV infection in a human, comprising administering to said human a therapeutically effective amount of one or more antibodies or fragments thereof that immunospecifically bind to one or more RSV antigens, wherein a certain serum titer of said antibodies or antibody fragments is achieved in said human subject. The present invention further encompasses compositions comprising antibodies or fragments thereof that immunospecifically bind to a RSV antigen, and methods using said compositions for detection or diagnosis a RSV infection
摘要:
High potency antibodies, including immunologically active fragments thereof, having high kinetic association rate constants and optional high affinities are disclosed, along with methods for producing such antibodies. The high potency antibodies disclosed herein are of either the neutralizing or non-neutralizing type and have specificity for antigens displayed by microorganisms, especially viruses, as well as antigenic sites present on cancer cells and on various types of toxins, and the products of toxins. Processes for producing high potency neutralizing antibodies and increasing the potency of already existing neutralizing antibodies are also described. Methods of using said antibodies in the prevention and/or treatment of diseases, especially diseases induced or caused by viruses, are disclosed.
